ADJUSTABLE AXLE FOR PLOWS, PLANTERS, AND THE LIKE.

Specification of Letters Patent.

Application filed August 1, 1912. Serial No. 712,716.

,To all whom it may concern:

Be it known that we, WILLIAM F. DALLEY and DAVID A. TREVEY, citizens of the United States, residing at Ira, in the county of Scurry, State of Texas, have invented a new and useful Adjustable Axle for Plows,

Planters, and the like, of which the following is a specification.

The present invention relates to an adjustable axle for use in connection with wheel mounted or sulky plows, of the middle burster or lister type, or for use in connection with planters and other devices for tilling or working the soil. 1

In present day wheel mounted or sulky plows or planters of the character indicated, the axles are generally straight,'which provide for several disadvantages in the use of a plow or planter embodying such an axle. In a case of a middle burster or lister plow, the ordinary straight axle causes the plow to be tilted to one side when the wheels are traversing uneven soil, so that'in bedding the soil, should the axle be thrown out of horizontal position due to the unevenness of the soil, the plow will cause the beds on the opposite sides to be uneven. In case of a planter, the plow thereof will also be caused to tilt to one side should the soil be uneven which would cause the bed to be burst to one side ofthe center, which is objectionable. 7

The foregoing and other disadvantages have been overcome by the provision of a. 7

novel form of adjustable axle, which permits the plow to run even at all times, notwithstanding the unevenness of the soil.

It is also the object of the present invention to provide an axle of the character in dicated, which shall be simple, substantial, compact and inexpensive in construction, as well as convenient and efiicient in use.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

The invention has been illustrated in its preferred embodiment in the accompanying drawingswherein,

Figure 1 is a perspective view of an axle constructed in accordance with the present invention. Fig. 2 is an end elevation thereof. Fig. 3 is a sectional detail taken on the line 33 of Fig. 2.

Referring specifically to the drawings, the numeral 4 designates the straight section of the axle, which has aground wheel 5 ournaled on the outer end thereof, or secured rigidly on the outer end, the latter being the case when a planting mechanism or other device is to be actuated from the section 4 of the axle. The inner end of the section 4 is j ournaled through the bore 6 of a double journal box 7, the said j ournal box having a second bore 8 parallel with the bore 6. The journal box is relatively small and compact and the bores are arranged in close relation. Cotter pins or other retaining members 9 are engaged .to the straight section 4: at the ends of the journal box 7 so as to constrain the journal box and straight section A against longitudinal or sliding movements relative to each other, but at the same time to permit the straight sect-ion lto rotate relative to the journal box. The j ournal box 7 is provided at its outer end with a boss 10 projecting from around the correspondlng end of the bore 8, and to the said 'boss 10 is secured a toothed segment 11 which passes over or past the inner end of the section 4 of the axle. This segment 11 is secured to the boss 10 in any suitable manner.

The numeral 12 designates the short cranked section of the axle, which with the straight section A completes the axle proper, the journal 13 of the cranked section passing through an opening in the segment 11 and through the bore 8 of the journal box. A cotter pin or other retaining member 14: is engaged to the journal 13 at the inner end of the journal box for retaining the cranked section and journal box against separation and permitting the cranked section to swing or turn relative to the journal box. On the spindle 15 of the cranked section 12 is mounted the other or opposite ground wheel 16, the same being mounted loosely on the spindle so as to be rotative relative thereto. A lever 17 has an eye 18 at its inner end engaging the journal 13 of the cranked section 12 adjacent the segment 11,'and the said lever 17 is also provided with a spring pressed manually actuatable pawl or dog 19 adapted to engage the teeth of the segment 11. The lever 17 and the cranked section 12 are connected by a diagonal brace or rod 20, which has its ends bent angularly and engaging the said parts. The lever is thus attached to the cranked section and removable therewith. A suitable brace 21 is secured to the bottom of the journal box 7 and is connected to the tongue 22 of the plow or planter, or to any other suitable part of the iramework, which is mounted on straight section 4 of the axle. The plow or other soil engaging device is carried by the frame mounted on the straight section 4, the plow and frame not being shown, as the same forms no part of the present invention. The brace 21 constrains the double journal box 7 against rotation.

Ordinarily in the use of a plow or planter embodying the present axle, the lever 17 is adjusted so that the cranked section 12 of the axle lies in the horizontal plane of the straight section 1. Should the soil be uneven, or sloping, the wheel 16 may be raised or lowered relative to the wheel 6 by swinging the lever 17 after the pawl or dog 19 has been disengaged from the .teeth of the segment, and after the lever has been properly swung, the pawl or dog may be permitted to engage the teeth of the segment so as to retain the wheels in set position relative to each other. It will be clearly apparent, that when the lever is swung, the cranked section 12 will be swung accordingly so that the wheel 16 will be raised or lowered relative to the straight section 4 which will permit the plow or other device to run properly over the soil.

Particular attention is directed to the fact that the present axle is applicable to various plow structures, and the like, the long section being attachable to various plow structures with the lever and cranked section located at one side, and the journal box being adapted to be secured to the structure at the various positions about the axis of the long section so as to normally position the cranked section as desired or according to the circumstances.

The present axle is simple, which is a requisite necessary in order that it may be ap plied to various structures with equal effect and propriety.

From the foregoing, taken in connection with the drawings, it will be apparent that the present axle obviates the objections noted, and provides a desirable device of the character indicated for the purposes stated.

Having thus described the invention, What is claimed as new is:

A device of the character described comprising a long straight axle section, upon which a structure may be mounted to be carried thereby, a journal box through which one end of the said section is journaled, a short crank section having its journal j ournaled through the said journal box adjoining the journaled end of the said straight axle section, the journal box having a. boss surrounding'the said journal of the crank section, the journal box being adapted to be attached to the bottom of one side'of the said structure, a segment secured to the said boss, a lever having an eye embracing the journal of the crank section adjoining the segment, means connecting the lever and crank section, means carried by the lever engageable with the segment, and ground wheels carried by the remote ends of the said sections.

In testimony that we claim the foregoing as our own, we have hereto .aflixed-our signatures in the resence of two witnesses.
